Magellan SD files (as for eXplorist) (magellanx)

This is the SD card format used by the Magellan Explorist 400,
Explorist 500, Explorist 600, and Explorist XL and internally on those devices plus the
Explorist 210. Stored waypoints are identical to the Magellan SD format
used by Meridian, but the newer models allow longer waypoint names. Routes are
subtly different.

You should name any file containing waypoints created with
this format with a ".upt" extension so the firmware can read it.
Similarly, routes should be named ".rte" and tracks should be
named ".log".

deficon option

Default icon name.

The deficon option is used to control the icon output when writing to this format. It overrides any icon information that might be present in the source data.

maxcmts option

Max number of comments to write (maxcmts=200).

The maxcmts option allows you to specify the number comments that will
be sent to the unit.

Magellan receivers allow a maximum of 200 waypoint comments. Unfortunately,
DirectRoute uses waypoint comments to provide next turn directions for
navigation pop-ups and that comes from that pool of 200 comments. It
is therefore sometimes convenient to limit the number of waypoint
comments written to the receiver. For example, a geocacher might want
to upload 400 waypoints, but only 190 with comments so that DirectRoute
could provide driving directions for the next ten turns.
